BLANK BOOK FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 470,769, dated March 15, 1892.

Application filedDecemher 2, 1891. Serial No. 413,768. (No model.)

To all whom itmay concern.-

Be it known that I, CHESTER G. THOMSON, of Lafayette, county of Tippecanoe, and State of Indiana, have invented certain new and useful Improvements in Blank Books for Type-IVritcrs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts.

My invention relates to improvements in the construction of books whose pages are intended to be detached for use and reunited after being printed by a type-writer, and is an improvement upon the book shown in Letters Patent No. 446,095, issued to J. H. Fitzgerald, February 10, 1891, and will be understood from the following description.

In the drawings, Figure l is a perspective View of an open book made upon my plan. Fig. 2 is a sectional view of the two leaves shown in Fig. 1, the left-hand one having been detached and reunited by means of the uniting-strip, as hereinafter described, the right-hand one not having been detached. Fig. 3 is a perspective view of one of the leaves which has been detached, showing a slight modification in the manner of reuniting the parts.

In detail, 1 are the leaves of a book, 2 the stubs, and 3 a line of perforations between the stub and the leaf, so as to permit the latter to be detached readily.

- 4 is a uniting-strip, gummed upon one side and preferably made of bank-note paper or other tough material.

5 is a recess in the leaf, formed bya pressure-roll or other device, a short distance on either side of the line of perforations, thus forming a seat to receive the uniting-strip 4, and this strip, when applied as hereinafter described, will adhere to the stub and to the leaf and will fit into the recess or seat 5 in the manner shown at the left hand in Fig. 2, and the thickness of the reunited parts will be substantially that of the leaf on one side and the stub on the other.

In the device of Fitzgerald the leaf, after having been separated and imprinted upon by the types, is reversed and turned over and pasted down upon the stub a little distance back of the line of perforation, the corresponding part of the leaf having been gummed for that purpose, and this reduces the width of the re united'leaf, and correspondingly of the book. When his book is made, the pages have to be numbered at the bottom and in reverse order to allow the book when the pages are again united to present the paging in numerical order and in a proper position at the upper right-hand corner of the page.

By means of my improvement there is no necessity for the numbering of the pages at the bottom or of reversing the leaves whenthey are to be reunited to the book.

The following is the manner of using my book, and may be illustrated particularly by reference to the figures of the drawlngs. If the right-hand page of abook 61, as shown in Fig. 1,is to be used, it is detached or separated from the stub along the line of the perforations 3, and it is then put into the typewriter and the matterimprinted thereon, and

when the page is filled or all the matter that is to be put thereon has been imprinted it is laid back in its former position, the edges of the perforations being joined as closely as practicable, the strip 4 is dampened, so as to partly dissolve the gum, and laid under the edge of the stub and the edge of the leaf which are to be reunited a corresponding distance on either side of theline of perforations, and the leaf and stub when thus set in proper place are pressed down upon the strip and the leaf turned over, and the strip smoothed and pressed flat over the line of junction, and when completed it will appear as shown in page of the book shown in Fig. 1, and the relative position of the gummed StI1p4 with reference to the depression in the leaf and stub will be as shown at the left hand in Fig. 2. By this means the parts are thoroughly and completely united, and a hinge is formed by means of the gummed strip, which will resist ordinary wear.

The modification shown in Fig. 3 differs slightly from that shown in Fig. 2 in this, that the edge of the paper is lapped over upon the stub, and one or the otheris gummed, so

as to reunite them along the upper side of 100 the stub, while'the uniting-strip 4 is placed beneath both, a part of it .restingin a depression in the stub and the other resting directly upon the back of the leaf; but the section united by a section of less thickness perforated through and across such thinned section, in combination with a strip of adhesive material adapted to fill such thinned section for uniting the leaf and stub sections, substantially as shown and described.

3. A blank book for type-writers, consist ing of a series of leaves or pages each havlng thinned sections across its width between the stub and the leaf portions and perforated to allow the leaf to be detached from such stub,

in combination with a uniting-strip for filling the thinned section and suitable adhesive material for uniting the parts, substantially as shown and described.

In witness whereof I have hereunto set my hand this 26th day of November, 1891.
